Nat bought 3 colas for $1.25 each, 2 hot-dogs for $2.50 each, and a hamburger for $6.50. He paid with $20 bill. How much money does Nat have left.

Answer 1

Let's start by totaling up how much the food costs:

3 * $1.25 = $3.75

2 * $2.5 = $5

1 * $6.5 = $6.5

$3.75 + $5 + $6.5 = $15.25

And now subtract that from the bill:

$20 - $15.25 = $4.75
